As we reported last week, there were numerous problems with the MacBook Air firmware update released earlier in the week. Users reported symptoms as innocuous as the update simply not being applied, to preventing the laptop from rebooting. In most cases, performing multiple SMC resets on the computer fixed the booting problem, but the update was still not installed. A few users found that even though the System Information application reported that the firmware was not updated, afterwards their MacBook Airs began suffering some of the problems that the 2.9 update was supposed to fix. Some of the symptoms included trouble reconnecting to wifi networks, fans unnecessarily running at full speed, and issues with sleeping and waking the computer.

Let than a day after the reports began flooding in, Apple removed the update from the App Store and users were no longer getting prompted to install it. As of today, a newly numbered 2.9.1 update can be found appearing in the App Store under Updates. Owners are cautioned to hold off on applying the new update, unless necessary, until reports come back that the install is working correctly. We will keep you updated as reports come in and the situation develops.

Per TechCrunch, Facebook has announced that the service will stop allowing messaging in its main iPhone and Android apps, and force all their users around the world to download its standalone Messenger app. Facebook first started requiring users in Europe to use Messenger back in April, but after seeing “positive results” in terms of engagement, has begun rolling out the plan to its entire user base. The company has stated that people on Messenger reply about 20% faster, and not supporting multiple version of mobile chat will help it make both its main apps and Messenger better.

Mobile web, iPad, feature phone, Windows Phone, Paper, and desktop users can still message in their main Facebook apps or sites like before, and will be spared from this forced migration for now.

Apple might not be able to deliver the anticipated sapphire display covers for the iPhone 6.

Per market research firm TrendForce, the new feature seems unlikely thanks to poor yield rates for sapphire ingot and problems with the processing of the material, according to a new report, which suggests that Apple is unlikely to ship a sapphire-covered device in large quantities this year.

Downstream component makers would have had to begin shipping the sapphire display covers to Apple’s assembly partners in June to meet the company’s September deadline, according to the report, but those shipments have not yet appeared. This is likely to point to either a delayed or seriously constrained release for a sapphire-covered iPhone, the firm argues.
